How to define different yaml for different branch in azure pipeline? – Ubuntu

I have a build pipeline for my project setup on azure.
This project has 2 branches: master and iis.
I also have 2 different pipeline yaml files for these branches.
For master branch, I want it build with yaml1. For iis branch, it needs to grab yaml2.

Most of the parts inside these yamls file are the same, except the pool name. For master branch, I have azure hosted agent while for iis, I use our own microsoft hosted agent.

How would I achieve this without creating another build pipeline ? Thank you

Yaml1:

    I ended up not to use template, because that would require me to have another 2 yaml files. Instead, I use if else expression in pipeline variables to determine which pool that I should run based on the branch. That way I still have only one yaml file :)

    Consider using of templates and switch them with if.

    In this case for steps, you may have something like that:

    steps:
${{ if eq(variables['Build.SourceBranchName'], 'master') }}:
  - template: templates/for-master.yml
${{ if eq(variables['Build.SourceBranchName'], 'iis-dev') }}:
  - template: templates/iis-dev.yml
